# EpiSAM: Weights
[Project Website](https://ihdia.iiit.ac.in/episam/)
**For EpiSAM dataset refer to the project website.**
We provide two weights:
- `episam.pth` is the checkpoint for the segmentation module.
- 'binarizer.pth' is the checkpoint for the binarizer used in the self-prompting module. For more details on this refer to the [Shilalekhya Binarization](https://ihdia.iiit.ac.in/shilalekhya-binarization/) website.
Training code is provided in the [GitHub repository](https://github.com/ihdia/episam/) for EpiSAM.
